FRAME FOR MAGNlFYlNG-GLASSES- No. 839,599. Specification of LettersPatent. Patented Dec. 25, 1906,

Application filed February 4,1905. Serial No. 244,163.

all the parts are assembled is adapted to en gage with the ends of thespring member D.

The spring member D is provided at its central portion with wmgs 13,extending out from its longitudinal side edges, as is particularly shownin Figs. 1 and 3, and these wings 13 are secured to central enlargedsections 14 of the connecting members C, the said members being two innumber and located one at each side of the body portion of the spring,so that, it will be observed, the spring is entirely free from the pointwhere the wings 13 are located to the ends of the said spring.

A knuckle 15 is formed upon the inner face of each connecting member Cat each end thereof, and the lugs 11 are placed between the saidknuckles or connecting members, and suitable pintles 16 are passedthrough the knuckles and through openings in the lugs, as is illustratedin Fig. 2. Thus it will be observed that one ring member is at one endof the connecting members while the other ring member is at the oppositeend of said connecting members and that the lugs 11 of the ring membershave bearing against the inner face of the spring D.

The larger ring member A may be termed a supporting member, while theopposing member B may be termed a lens member. When the device is to beused as an eye glass, the two ring members are placed in the positionshown in Figs. 1 and 2-, at right angles to the connecting nembers, andthe ring member A is then placed in the eye-socket i and is held inposition at the eye in the same nianner as is an ordinary watchmakerseyeg ass.

To all whont it may concern:

Be it known that I, \YILLIAM J. KEMLER, a citizen of the United States,and a resident of Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented a new I and Improved Frame forMagnifying-Glasses, of which the following is a full, clear, and exactdescription.

The purpose of my invention is to provide a frame especially adapted formagnifying glasses, so constructed that it can be compactly and flatlyfolded when not in use and quickly and conveniently opened out for useas a standing frame or an eyeglass-frame or so that all the members areplaced in practically horizontal alinement, in which latter position ofthe parts one member can be utilized as a handle and the lens memberemployed for reading purposes, thus enabling the same device to be usedas an eyeglass, a standing view or magnifying glass, and areading-glass.

The invention consists in the novel con- 1 struction and combination ofthe several parts, as will be hereinafter fully set forth,

and pointed ou in the claim.

Reference 1s to be had to the accompanying drawings, forming a part ofthis specification, in'which similar characters of reference indicatecorresponding ures.

Figure 1 is a perspective view of the device adapted as an eyeglass andwhich by being inverted can be utilized as a standing view or magnifyingglass. Fig. 2 is a longitudinal section taken practically on the line 22 of 1, illustrating in dotted lines the first position of the parts infolding. Fig. 3 is a parts in all the figplan view of the device folded,and Fig. 4 is a If it be desired to examine an object, the ongltudinalsectional view of the device device is snrply mverted and the largerring member A will then support the device and is placed around theobject to be viewed, thus bringing the lens niember B uppermost. Whenthe device is to be used as a reading 1 opened out to its full extentand adapted for use as a reading-glass.

The device consists practically of two ring members A and B, connectingmembers C, and a spring member D. The ring member A is of greaterdiameter than the ring member B, and the latter member is adapted toglass, the supporting 1r ember A and the lens member B are both foldedout to their full extent, bringing all the parts in substantially clampa lens 10. Each ring member A and the same horizontal plane, and undersuch B is provided with a lug 11, extending from conditions thesupporting member A is utilits peripheral surface, and each lug 11 isenized as a handle.

larged at its outer end, and said outer enhen the parts are in theposition shown larged end is provided with a flat bearingin Figs. 1 and2 and it is desired to fold the desurface 12, which bearin -surface 12when vice flat, the lens member B is first folded onto the connectingmembers, and then the connecting members and the lens member are carriedupward, as is shown by dotted lines in Fig. 2, until the lens memberenters the supporting member A, the connecting members crossing both thesupporting and %he lens members A and B, as is shown in It 'will beobserved that when the parts are in the position shown in Figs. 1 and 2the bearing-surfaces 12 of the lugs 11 on the supporting and lensmembers A and B have such engagement with the free portion of the springD as to hold the said members in their adjusted position until they areforcibly carried from the same; but when the parts of the device arecarried to the position shown in Fig. 4 the side faces of the lugs 11 onthe supporting and lens members A and B have such an extent of flatbearing against the ends of the spring as to effectually prevent thesaid members A and B from being car ried farther toward the back of theconnecting members, thus compelling all of the members to be insubstantially the same horizontal plane, yet all of the members may bereadily manipulated to carry them to the folded po sition shown in Fig.3.

spaced apart, said plates being provided with opposing knuckles on theirinner sides adjacent to the ends thereof, a flat spring of approximatelythe same length as the plates and provided with lugs projecting from itsside edges at the center of length thereof, said lugs being secured tothe inner sides of the said plates, a supporting-ring, a lens-ring ofless diameter than the supporting-ring, each ring being provided with anapertured lug projecting radially from its periphery, said lugs beingenlarged beyond the apertures and having flat end bearing surfaces, andpintles passing through the knuckles of the plates and the apertures ofthe lugs of the rings.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. v

WILLIAM J. KEMLER.
